Subject [jira] Commented: (DERBY-1648) Create a tool for salvaging data from a database that will not boot.
Date Fri, 12 Jun 2009 18:32:07 GMT

    [ https://issues.apache.org/jira/browse/DERBY-1648?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12718934#action_12718934
] 

Kathey Marsden commented on DERBY-1648:
---------------------------------------

There was a thread on derby-user with a proposed alternate solution to this problem which
might recover more data and in a more consistent state.  The idea is to provide a property
which allows users to skip problematic log records so they can boot and then drop the offending
index or table.

> If  a Derby database is corrupted  by dual boot or for some other reason, it is really
necessary to create a new database and transfer the data.  Currently there is not a utility
to do this.
> It would be good to have a tool which given a corrupted database would attempt to salvage
the data it can  by creating a new database and transferring the data while preserving the
state of the original corrupted db for analysis
